Push Button

A pig pushes a button on a box, which makes a sound and then a crashing noise. The pig finds this very amusing and pushes it several times until he gets bored. He walks around and discovers a bunch of pigs that have been smashed in on the ground. Then he hears the sound and a weight from above almost smashes him. He dodges several of these, then chuckles, but then he got smashed in as another pig has pushed the button. After that, laughing sounds can be heard.
